v The object of this invention is to practically utilize kerosene or even the heavier hydrocarbon oils, as gasolene is utilized, in the following manner-viz. ,by vaporizing itand consuming the vapor in a gas-burner or in an explosion-engine. Many efforts have been made with this end in view; but to the best of my knowledge and belief none of these. efforts have resulted in any satisfactory degree of practical success. In my judgment the rea son for this lack of practical success has been the failure to appreciate this fact-to wit, that although it requires a higher temperature to vaporize kerosene than to vaporize gasolene the kerosene-vapor will be disrupted by high temperatures which will not injuriously aifect gasolene-vapor. The result of this disruption by unduly high temperatures is that the appa ratus into which the vapor. is delivered becomes clogged up by carbon or by a sticky heavy hydrocarbon. This happens in burners 1n which it is attempted to burn this vapor and in the explosion-chambers and cylinders of explosion enginesin which it is attempted. to -use it. Kerosene-vapor which has been; sub ect to too higha heat will not be perfectlyv consumed in either of the two places referred to. To-prevent the disruption of'the kero- 49 1 struction and combination of parts for vapor-- being overheated. 4 The present invention consists in the consene-vapor, it is necessary to prevent it from izing the kerosene and automatically maintaining the temperature of the vaporwithin safe limits.

The invention consists ,in a generator for containing the oil tobe vaporized, a gas-.

burner for heating thegenerator, a valve for controlling the flow of gas to said burner; and a thermostat arranged so as to be. under the influence of the heat of the vapor in the generator, which thermostat is operatively connected with said valve.

1 It also consists in the more specific combinations of parts hereinafter described, and pointed out definitely'in the claims.

Figure 1 is a side elevation of a device employing my-invention, the thermostat, a part of the generator which contains the thermostat,and the casing-0f the valve which the.

thermostat operates being in vertical" section; and Fig. 2 is a vertical sectional view in the plane indicated by the bent line 229i Fig. 1. j Y Referring to the parts by letters, A represents a generator, which may. beof any suitable constr'uction adapted to contain the kerosene to be vaporized and to be heated by a gas-burner. ing of a plurality of convolutions a, connected in series and arranged one above another,'substantially as shown, is employed. The oil is Preferably a generator consistadmitted to the upper convolution through an inlet-pipe a; and after the generation of the vapor has been begun theoil ma have to be forced into the generator against some pressure due to the pressure of the vapor inv the lower coils.

, D represents a'gas-bnrner arranged beneath the generator.

C represents the discharge-pipe of the generato'r, through which. the vapor. may be conducted to'the point at which it is ,to be usedf Connected with this discharge-pipe is a branch pipe E, which leads to the burner D, wherefore the vapor generated in the generator is partly utilized for producing the heat by which such vapor is generated. lnthrs branch pipe is a valve e, which controls the flow of gas to the burner. In the generator, and preferably in that part thereof which will con-" only the kerosene-vaporto wit, in the lowest coil, as shownis a thermostat F. Preferably one substantially like that which I is shown in my Patent No. 676,790, is employed, and the mechanism intermediate of the expansible rod f, forming a part of the thermostat and transmitting motion from it to the valve, is substantially like that which is also shown in said patent, consisting of a bell-crank lever G, which engages a shoulder e in the valve-stem.-

The thermostat, as shown, consists of a copper tube f, which is closed at one end. The open end is tightly fitted in an opening -.in one side of thevalve-casing. An iron rod f passes through this opening and through the copper tube, and one end thereof is rigidly fastened to the .closedend of'the copper tube. Owing to the difierence in the coefiicients of expansion of this copper tube and iron rod, it will be seen that as the heat operating upon this thermostat increases the copper tube will lengthen more than the iron rod will, and therefore the end of said rod within the valvecasing will be drawn away from the valve, permitting the valve to close.

It will be understood, of course, that other forms of thermostat may be employed and that other mechanism may be employed to transmit motion from the thermostat to the valve.

What is' necessary generally to carry out my invention is to have the generator heated by a gas-burner, to have the supply of the gas to said burner regulated by a thermostat in the generator, and any construction employing the parts referred to in substantially the manner herein shown and described is intended to be included in my claims.

In the drawings, Fig. 1 is a side view of an apparatus embodying my invention when the lower coil ofthe generator and the valve-casing .are sectioned. Fig. 2 is a sectional .end view on line 2 2 of Fig. 1.

Having described my invention, I claim- 1. The combination of a generator containing oil at all times, a gas-burner for heating the same to vaporize said oil,a' valve for controlling the flow of gas to said burner, and a thermostat for controlling said valve and arranged to. cause the valve to move in the closing direction to reduce the gas-supply of said burner when the heat ofthe generated oil-Va,-

por reaches a predetermined maximum and to move in the opening direction as the temperature of said vapor is reduced,thereby prevent oil-vapor, substanv latter will be opened when the temperature within the generator falls below a predetermined minimum-and will be allowed to close when said temperature goes above a predeter mined'maximum, substantially as specified.

In testimony whereof I hereunto aflix my 1 signature in thepresence of two witnesses.
